A manager at Chemical Bank in Midland, Michigan, grew suspicious when he saw Marion Case, an 80-year-old customer, withdraw $25k from her account last December. Case told him she was going to mail it to someone who would then pass it along to her son. The manager, Carl Ahearn, “remained suspicious. He followed her as she walked to the nearby post office, where Case bought an Express Mail envelope addressed to a man in New Jersey. Ahearn shared his concerns with postal officials, who opened an investigation and arrested a man Monday for fraud.”
